high load on hosts
by Jayme 24 Oct '18

24 Oct '18

I'm wondering how I can best limit the ability of VMs to overrun the load on hosts. I have a fairly stock 4.2 HCI setup with three well spec'ed servers, 10Gbe/SSDs, plenty of ram and CPU with only a hand full of light use VMs. I notice when the occasional demanding job is run on a VM I'm seeing load average on host node shoot up in to the 20-30s, how can a single "medium" vm cause host load to rise so high?

Choosing optimal vdo Write policy on LSI Raid device that always report write-trough to the OS
by guillaume.pavese＠interact-iv.com 24 Oct '18

24 Oct '18

Hi, I am evaluating vdo for an hyperconverged ovirt cluster. The volume is on RAID device supported by a LSI (Dell Perc H710) controller with Write Back cache enabled : Current Cache Policy: WriteBack, ReadAdaptive, Cached, Write Cache OK However these LSI controllers (all PERC series on Dell servers), as per documentation, always report cache policy as writethrough to the OS, no matter if write back is effectively enabled or not : cat /sys/block/sdb/device/scsi_disk/0\:2\:1\:0/cache_type write through vdo by default choose its write policy (sync or async) accoring to the cache mode reported by the disk. So with cache policy auto, in that case it is set to "sync" : write policy: sync So my question : In this configuration, write cache enabled on the raid controller but reported as write trhough to the os, should I manually set vdo cache policy to async for optimal performance? Thanks for your help

Import VM from VMware OVA
by Hari Prasanth Loganathan 23 Oct '18

23 Oct '18

Hi Team, 1) I exported a ovf file from VMware 2) I converted the ovf file to ova using ovftool successfully. 3) I imported the ova using the VM Import -> VMware appliance OVA -> provided the path of the ova (copied in ovirt location) 4) VM is successfully imported into the ovirt and I see the disk is also successfully imported BUT the disk is stored as image disk, What is the possible way to import the VM (as mentioned above) and store the disk as Cinder disk (currently always it is storing as image disk type) Any help is much appreciated.
